In the last decades lithium-ion (Li-ion) batteries are the premier choice for clean and efficient energy storage for portable devices and electric vehicles. However, their performance still falls short due to the low energy density 100-265 Wh/kg. Anodes for Li-ion is exposed to volume expansion during the discharge-charge cycling that leads to cracks and losing the electric contact. Study will be focused on developing novel binders based on self-healing polymers based on different healing mechanisms for Li-ion batteries. The polymer material will be designed to contain different functional groups in different molecular levels promoting either the hydrogen-bonding self-healing mechanism or the thermally reversibly healing mechanism for anode materials. Effect of the quantity and the type of the functional groups will be controlled via advanced approaches. The chemical modification of the natural polymers will be demonstrated using spectral analyses such as FTIR and NMR. Different anode composition will be considered to obtain high specific capacity which will be determined using El-cell to conduct full electrochemical measurements.
